Özet

This study addresses the influence of the carrier density on the critical temperature of layered superconductors by using the real dependence of density of states on energy in the framework of ordinary Bardeen-Cooper-Schrieffer (BCS) model. It is shown that such a model is in good agreement to obtain experimental data for new NdFeAsO1-y superconductors.
